To all w/w'm Zi may content:

Be it known that l. Bt'nxnmt C. STICK- KEY, a citizen of the UnitedStates, and resident of the city of Elizabeth, county of Union, andState of New Jersey, have inented certain new and useful ,iniprove-lments in Typell'riting Machines, of which the following is aspecification.

This invention relates to writing machines, and particularly to themechanism for controlling the letter-feeding movements of the paper orother carriage; and its principal object is to enable the carriage tofeed accurately at high speed, and to avoid liability of blurring of thetype impressions.

My inventionconsists in certain teatures of construction andcombinations of devices, which will be hereinafter fully described andparticularly pointed out in the concluding claims.

In the drawings forming part of this specification, Figure 1 is a rearview of a portion of a type-writing machine, showing acarriagefeedingmechanism and part of a carriage, and illustrating aconnection from the type-operating keys or levers to thecarriage-feeding mechanism: the parts being in normal position. Fig. issectional view taken at about the line U-ZU of Fig. 1. Fig. 3 is a. viewof a.inoditicatioi1. Figs. 4, 5 and 6 illustrate successive stages inthe action of the feeding mechanism. Fig. 7 is a diagrammaticrepresentation of a conventional system of. typewriter type-actions.

My invention may be applied to ,anyvariety of paper or other carriage 1,propelled by ni'eansof a spring-barrel 2 and strap 3 or otherwise, andhaving an escap'einent or feeding rack 4, which may be either straight,as illustrated, or curved, as a wheel. The rack tooth or teeth may be ofany suitable construction. Y

In engagement-with the rack is a dog 5, which extends along the rack andis provided witha tooth 6 for engaging the-rack teeth, and is pivotedupon gudgeons 7,

-which are supported one at each side of the rack upon the ,"upstandingarms 8 of a bracket 9; said dog having upwardly extending ears 10, oneat each side of the rec,

which are slotted at 11 for engaging said' .gudgeons; said slotspermitting limited play of the dog longitudinally of the rack. Qne

ear ,is prolonged to form an upwardly exnism is operated.

tending arm 12, into the upper end whereot" direction from that in whichthe carriage and rack are propelled by the superior spring andpreferably the relation of spring 13, arn1 12 and dog 5 are such thatthe same spring also tends to press the tooth 6 into engagementwith therack teeth, the body 5 and the arm 12 of the dog forming a hell-crankfor this purpose. It desired, the upward movement of the dog may be.limited by an overlying stop 15, supported upon a fixture 16 rising-fromthe usuahtop 'plate 17 of the typewriter, so that when the rack at islifted it may become disengaged from the dog. thereby releasing thecarriage.

Upon an extension 18 of the dog, over which lies said stop 15, is formedat its tip a series offine teeth 19. for engagement with a set of tineratchet-teeth 20; all of said fine teeth extending in. a directiontransverse to thecarriage racks, and the function of the ratchet teeth20 being to pull the dog down out of engagement with the rack teeth. Theteeth 20 are formed upon an operating ratchet member or pawl 21 which ispivoted at 22 upon an arm 23, the latter being mounted at 24 upon ahanger 25 and provided with a shoulder 27 and stop The arm and pawlarcoperated in this instance by means of a universal-bar 29 extendingtransversely above upwardly movable keys or key-levers 30 forming partsof the printing devices, 2'. 6., p

the deviceswhich operate the types or type bars; said universal barbeing connected by a link 31 to a pin 32 on said-arm 23, and the linkbeing slotted at 33 where it engages said pin, so asto permit some lost}motion of the keys before the feed mecha- A draw spring3e is attached at35 to the ratchet member 21 between its ends, and extends diagonally toa point of connection with a, fixture 36, in a manner to pulldownthepawl and the arm 23 after actuation, and alsoto press the ratchetteeth 20 toward the dog tooth or teeth 19; a stop 3'Z tor the ratchetpawl 21 being provided however upon the top .plate, to prevent said pawlfrom following the dog during thelhackward movement of the so that the ftiq l et may finish its return 2 parts are inthe Fig, 4 position, thedog 5 not being moved-during the printing stroke. Upon the return strokeof the key, type and universal bar, the spring 34' pulls down the pawl,together with the dog, in opposition to "the tensionlof the spring -1"3;Whe1"eby the escapement member or toothfi is disengaged from thecooperating escapement or rack 4, as at Fig. 5. Upon the escapement ofthe dogfrom the rack, it is instantly snapped .'.back along ,the rackbythe spring l3, as far as permitted by length of 'the""'slot"11,.

whereby the dog teeth 19 are withdrawn from the ratchet 20, ,and the dogis released,

stroke 'independentlyof the dog, and the latter is pressed back intoreengag'ement with thefrack l independently of the ratchet 5 thekey-operated parts return ng to norma1 position,-and the carriageadvancing underthe tension of spr1ng2, carryin with it the dog 5 inopposition to: the-tenslon of spring 13, until the-dog and carriage arearrested by 'the contact of-the gudgeons 7 .with the rear ends ofth'slots 1 1, the parts being again brought to the Figal position.

It will. be seen that the dog is. normally I disconnected from the keys,'in the sense that the 'keys'do notaffect-the dog during their printingst-rokes, and that the period during which the dogis connected to thekeys isvery brief, and only sufficient to enable the dog to bedisengaged from the rack all of thes subsequent operations of the dogbeing automatic, -viz its release from the control of the keys, itsreengagement with the-rack, and its return to normal position, wherebyat the completion of the. carriage movement, the dog is in position forre-actuation during the return-stroke of the next-' op'erated'key. Bymaking these movements of the dog independent of the key move--'ments,the advantage is secured of speed and certainty of operation;while by having only one rack-releasing dog-movement instead of two asin the usual construction,

ease and speed of operation are-insured? The dog maybe provided ,withonly-one tooth1 9', and a single clutch tooth mayibe: used in place ofthe .clutci ng ratchet 20; but-I prefer to use the fincteeth as illllS-rtrated,because of the variations in t ex-l tent of movement of theuniversal? sates) given by the differentkeys; these variations much/thepawl 21 is elevated during the theprinting stroke in engagement with thedogtooth or teeth 19, and'since the teeth '20 are fine, only a shortportion of the return movement of the universal-bar is used in freeingthe dog tooth 6 from therack-{so .that the carriage is'promptly releasedand enabledto complete its feeding movement in time to receive the nexttype impression in some machines being very-great. Itwill 1 be seen thatnomatter how little or how f key stroke, it-is always at the completionof at the correct point, even at the highest speed of operation. To thisend of course the tooth 6 should be formed andmounted to dip into therack to a slight extent only,

so that it can be disengaged by a short .stroke. It will. be perceivedfurther, that the machine is fully adapted for slow operation, since thedog 6 holds the rack positively during the printing stroke; so that noblurring of the type impressions can occur.

iAt Fig. 3 the pawlor dog 5 is mounted upon ani idle link 38, pivoted at39 to car 40 rising from the top plate 17; said link being provided withcars 41 and 4-2, adapted to contact with stops 43 and 44;..thelinkpermitting'play of the dog longitudinally. of

the rack, and the stops being adjustable for limiting the extent of theplay. It will thus"- be'seen that the dog-disengaging means 20 ismovable transversely of the rack and is releasable from the dog by themovemhnt of the latter longitudinally of the rack by the i spring 13;that at Fig. 4 the dog-disengag ing means 20 is;b eginning its returnstroke,

and that the dog is held in engagement therewith by the rack- 1 6., iftherack,

were pressed'back at said figure, the dog would be moved by spring 13out of en'- gagement with the ratchet 20, 'soflthat' the latter couldnot afi'ect it; that the play of the I dog along the rack is less thanthe extent of the feeding movement of the rack, that is,

less than --thedistance between vadjolning teeth 5; that the (log iscself-releasing fr'om the ratchet 20 and is self-setting to positionforreengagement thereby, as distinguished from ordinary escapementmechanisms, in which both the rack-releasing andthe rackreengagingmovements of the dogor dogs are controlled 'by the universal bar, the

-latter being key-controlled ;'that the arm- 12 extends. transversely ofthera'ck 4;.tha't the key-controlled reciprocatory member. 20; is

movable idly with relation'to the dog dur .ing one stroke, andco-nnectible with the dog during the other stroke, and that the dog is,restored to its normal position independ ently' of said reciprocato'rymember; that;

the 1'1-1eans fyvhich .releases the do from said member 20 issoconstructed "as to rendered effective by the rack-disengaging movement;

of the dog; andtha-t' the dog lsrele'ased-frc the' ra ck .bynmans of a"pawl-and-r'atci';

mechanism. which may be made in a great variety of forms.

By the termpawl-and-ratchct mechanism I mean to include any equivalentclutching mechanism one member whereof is movableidle with relation tothe dog'5 during onestroke, which may be of variable extent, and alwaysautomatically connects with the dog at the initial portion 'ofthe otherstroke.

Very many variations other than those above alluded to may be madewithin the scope of my invention in the construct-ion, arrangement,anddetails of operation of the parts; and portions of my improvementsmay be used without others.
